福建省近岸海域环境水质及富营养化评价

An Assessment of Water Quality and Eutrophication about Offshore Marine Areas in Fujian Province

摘要根据《福建省近岸海域环境功能区划（修编）》（2011-2020年）中新划定的环境功能区，结合2012年福建省近岸海域环境功能区监测资料，对福建省近岸海域环境功能区进行水质评价及富营养化评价。结果表明，2012年福建省近岸海域环境功能区海水水质总体呈一般水平，海水总体为轻度富营养化，富营养化程度主要受无机氮和活性磷酸盐2项指标影响，化学需氧量对其影响不大。

According to the new definition of environmental function zoning in ＂Fujian Province Environmental Function Zoning Programme for Offshore Marine Areas （revision） （2011--2020）＂, and combining with the monitoring data in 2012, an assessment of water quality and eutrophication status in Fujian offshore marine areas was conducted. It has shown that the seawater quality of environmental function zoning in Fujian offshore marine areas in 2012 was at general or slightly eutrophic level. The eutrophication of seawater was affected mainly by inorganic nitrogen and active phosphate whilst chemical oxygen demand had a little effect.
